Each visit is a private 45-minute Fire & Ice circuit with sauna, cold plunge, and shower. Each location has rooms with traditional sauna for more intense heat and steam, plus infrared sauna options.
Start Hot
Begin with your preferred heat: traditional sauna for a hotter steam session, or infrared sauna for deep radiant warmth.
Go Cold
Step into the cold plunge for 1-3 minutes. Control your breath, stay calm, and let the cold do its work.
Repeat & Recover
Cycle between sauna and plunge for the full session, then rinse off and leave reset, clear, and recharged.
Feel calmer. Recover faster. Sleep better. Build resilience.
Contrast therapy gives your body a simple heat-and-cold reset, with research-backed benefits for cardiovascular health, brain health, longevity, and recovery.
